A sink – also known by other names including sinker, washbowl, hand basin, wash basin, and simply basin is a bowl-shaped plumbing fixture used for washing hands, dishwashing, and other purposes.”


Why Is My Kitchen Sink Leaking Underneath

The following are the seven common causes of kitchen sink leaking:

The Drain Leak

Your kitchen sink may be leaking due to a clogged drain. To avoid additional leaks, a drain is frequently sealed with plumber’s putty. The putty, on the other hand, may be too thin to begin with, or it may dry out over time. On rare occasions, the leak may be caused by an old and worn out drain that is beyond repair. In these cases, it is preferable to just call a plumber and have the drain fully replaced.

To find the source of the leak, just block your sink with the drain cover and fill it all the way up, then remove it. Use a flashlight to search beneath the sink for the cause of the problem.

In some cases, merely tightening the bolts at the junction of the pipes will solve the problem. In other cases, plumber’s putty will suffice. You may unplug the drain, repack it with new plumber’s putty, and then reconnect it.

Leaking Faucet

Leaks from the faucet are usually easy to detect. When someone turns on the faucet, water pools at the top of the sink, which is a frequent sign. A faucet leak might also flow beneath the sink, which means you’ll only notice it if you peek under the counter.

Faucet leaks are typically caused by worn-out gaskets or failing washers. All you have to do is swap them out. In rare cases, a serious leak will necessitate the replacement of the entire faucet, which is not a difficult task in and of itself.

Water Supply Connection That Isn’t Tight

If the leak beneath your kitchen sink is quite consistent, there might be an issue with the water supply line to your sink. A kitchen sink typically has two water supply connections, although there may be three if the sink has a separate sprayer. Each water supply connection has the potential to cause a leak and cause difficulties.

Because the connections are generally hidden, you might not detect a leak until it has drenched your cabinet and everything else in the under-sink storage. Corrosion or, more typically, a failing gasket in the connection might cause a water line leak. In most situations, replacing the gasket should be sufficient to stop the leak, but in others, merely tightening the connection should enough.

When it comes to buying a kitchen sink, there’s a lot to consider from the shape and size to whether you are purchasing just the sink.”


P-Trap Clogged

The word P-trap refers to the bent part of a pipe that is often located under the sink. Its primary function is to keep unpleasant odors from permeating the drains. Because the P-trap is frequently hidden, it is difficult to detect a leak immediately away.

Debris, tiny bits of food, and muck tend to accumulate at the P-trap over time. This prevents water from draining properly and may result in a leaky problem. Corrosion is another probable reason if your sink has metal pieces. If this is the case, you may need to entirely replace the trap.

O-Ring damage

The faucet handle is held in place by a stem screw. It has a little disc that is attached to it and is known as an O-ring. This is a frequent location for kitchen sink leaks. Because of constant usage, the O-ring might wear out or become loose over time, causing the faucet to leak near the handle. If the O-ring is damaged, replacing it should resolve the issue. O-ring issues are particularly common in cartridge faucets.

Washers That Have Worn Out

One of the most prevalent reasons of leaky sinks is a worn-out washer. The washer is forced against the valve seat every time you use the faucet. The continual friction causes the washers to wear down, at which point you will notice leaks around the spout. Sink leaks caused by worn-out washers are easily repaired by changing the washer. Worn-out washers are a typical issue with compression faucets.

Valve Seat Corrosion

The valve seat is intended to function as the compression mechanism’s link between the spout and the faucet. Water accumulation at the valve seat can cause it to corrode, causing the region around the spout to leak. It is strongly advisable to clean the valve seat on a regular basis with the aid of a skilled plumber.
